Partslist of the used components
- Remark: Some of the components used here seem to be very strange because they may be not available anymore on the market. The reason why I have used those components is very simple - I have just found them in my stock. Please feel free to use other components....
- The following components are used on my "prototype":

Used Power-Supply
- I've found a desktop-power supply which was originaI used for an external 5 1/4 inch hard-drive. It provides 12V / 2A and 5V / 2A thus exactly what is neede for the piano expander.
- 5V / 2A for the Joy-It Touch-Display
- 12V / 2A for the Odroid-N2
- The connector which was used on this power-supply was a Mini-DIN4 Power Plug (PP).
